OpenMotif provides a free version of the Motif toolkit for open source applications.
Multiple vulnerabilities, such as buffer overflows, out of bounds memory access or directory traversals, have been discovered in libXpm that is shipped as a part of the X Window System (see GLSA 200409-34 and 200411-28). OpenMotif, an application that includes this library, suffers from the same issues.
A carefully-crafted XPM file could crash applications making use of the OpenMotif toolkit, potentially allowing the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All OpenMotif users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose x11-libs/openmotif
Note: You should run 'revdep-rebuild' to ensure that all applications linked to OpenMotif are properly rebuilt.
